APPARATUS FOR FINISHING THE EDGES OF CARDS AND PAPER.

SPECIFICATION forming part of Letters Patent No. 416,869, dated December 10, 1889,

Application filed May 21, 1888.

I To all whom it may concern:-

in plan of the cutting-cylinder.

"opening at the edge of Be it known that L'EDSON J. SMITH, of Boston, in the county of Suifolk and State of Massachusetts, acitizen of the United States, have invented a new and useful Apparatus for Finishing the Edges of Cards, Paper, 850., of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification, in explaining its nature.

The invention relates to an apparatus for finishing or beveling the edges of cards, paper,

650., and which comprises, essentially, aclamp for presenting the edges of the cards or paper to a cutting disk or cylinder having cross clearing-recesses formed therein and separate or independent cutting implements extended therefrom into said clearing-recesses and beyond the surface of the disk or cylinder. This disk or cylinder is mounted upon a shaft, is adapted to be rapidly rotated, and for certain kinds of work is used in connection with a gage.

In the drawings, Figure 1 is a view in plan illustrating the invention and showing especially the manner of clamped cards to the cutting-cylinder. Fig. 2 is a view in end elevation thereof. Fig. 3 is a view in front elevation of the cutting-cylinder, its gage, shaft, andsupport for the same. Fig.4 is aview in end elevation thereof. Fig. 5 is a view in enlarged cross-secti0n of the cutting-cylinder. Fig. 6 is a View, enlarged, Figs. 7 and 8 illustrate a smaller cutting-cylinder than is shown in the other figures. Figs. 9 and 10 show cards the edges of which have been finished. Figs. 11, 12, 13, and 14: show different forms of cutting or gouging tools or implements.

A represents the cutting diskor cylinder. It is mounted upon a shaft a, supported by the bearings a, and having a fast pulley a and a loose pulley a The cylinder, preferably, is made of metal, and has extending across it from end to end the clearing-recesses a, which are preferably enlarged gradually from one end of the cylinder to the other. The cylinder also has the holes a extending across the same tangentially and having one a clearing-recess a.

presenting a stack of I Serial No. 274,488. (No model.)

cutter to be properly set after it has been ground.

The cylinder or disk may have one cuttingtool and clearing-recess or two cutting-tools and oneclearing-recess, as represented in Fig.

8, or it may have a larger number of cuttingtools and clearing-recesses, as represented in Figs. 5 and 6, where there are shown three clearing-recesses and three lines of cutting tools or implements, one for each clearing-re cess, and in this invent I prefer to arrange the cutting-tools so that no one of them shall come in line circumferentially with others back of it.

For certain work a gage is desirable, and I have represented it in Figs. 1, 3, and 4 at B, and as provided with a disk I), having a hub b, secured to the shaft a by a set-screw b and as also having a recess 12 in its face slightly larger than the cylinder A. This construction-via, the recess and the set-screw-enables the gage to be adjusted laterally in relation to the cylinder. The cards or paper are arranged in a stack and are held between the two blocks 0 c of a clamp O, the clamp having a screw 0 whereby one block is made movable and held in relation to the other block, and the cards are tightly confined in the clamp between these two blocks in a manner to expose the edge which is to be finished, and they preferably are arranged somewhat out of line, so that the edge of one card or.

paper extends slightly the one immediately over it. (See cards, sheets of paper, or other material to be finished in this manner and secures the same in the clamp, and then presents the edge or edges to be finished to the. cutting-cylinder.

If what is termed a ragged edge is required,

beyond the then the form of cylinder represented in Figs. '7 and S is preferable and the use of the gage is dispensed with, and the clamp is moved horizontally back and forth in relation to the disk or cylinder as it rotated. This produces a Very ragged and irregular finish capable of infinite variation. (See Fig. 10.) Vhen it is desired that only a portion of the edges of the cards or paper shall be finished by the cutter, then the gage Bis employed, and preferably a wider cylinder, and the clamp,instead of being moved horizontally, is moved vertically in relation to the cylinder, one edge of the stack of cards or paper being held against the face of the gage. (See Fig. 1.) This also provides the edge with a more regular finish-that is, each knife or cutting-tool of the cylinder removing only the paperupon a given line. (See Fig. 1.) The form of the finish, especially where it is a regular finish, depends upon the form of the cutting-edge of the cutting-tool. It may be rounded, as represented in Fig. 11, or it may be V-shaped, as represented in Fig. 12, or its edge may have any other desired configuration. The cutting tool is preferably formed of steel, and has its cutting-edge a formed by the bevel a, and the surface a preferably being flat. It will be observed that the surface a of the cylinder or disk acts as a rest, against which the edge of the assembled cards bears during the operation of the cutters, so that the cutters can make a out no deeper than the cutting-points extend from said surface.

Havin g thus fully described my invention, I

claim and desire to secure by Letters Patent of the United States- 1. The combination, with arot ry shaft, of a cylinder A, secured thereto and consisting of a single solid body having one or more longitudinal clearing-recesses extending entirely across its face, a smooth bearing-surface a between said recesses, tangential holes opening into said recesses, and radial holes opening into said tangential holes, the cuttingtools a in said tangential holes, with their cutting ends projecting beyond the surface of the cylinder at said clearing recess or recesses, and the set-screws a for securing said tools in place.

2. The combination,with a rotary shaft, of a cylinder A, secured thereto and consisting of a single solid body having longitudinal clearingrecesses extending entirely across its face, tangential holes opening into said recesses, and a smooth bearing-surface a between said recesses, and cutting-tools secured in said tangential holes and arranged out of line circumferentially around said cylinder.

3. The combination, with a rotary shaft, of. a cylinder A, secured thereto and having longitudinal clearing-recesses, a smooth outer bearing between the same, cutting-tools carried by said cylinder, and the rotary gage 13, secured to said shaft adjacent to said cylinder.
